{ ROLLER-BEABING.

To all whom it may concern Be it known that I, FRANK C. SEAMAN, a citizen of the United States, 'residin at Oneonta, in the county of Otsego and" tate of New York, have invented certain new and useful Improvements in Roller-Bearings, of which the following is'a specification jrefeb ence being had to the accompanyin ings. V I;

This invention relates to certainiinpno ments in roller bearings for hxlesg; like, and the object of the inve'ntitin provide a novel and improved device of general character havmg efi'eotive means whereby the amount of afriction between-the bearings, the axle or shaft and the ,hnhaogs box is reduced to aminimum.

The invention consists in the deteils'oii construction and in the combination ands?- rangement of the severalparts where!) ear-- tain important advantages are attain and; the device is rendered simpler, l's'siexpemive and otherwise more convenient andadvam tageous for use, all assvill be hereinafter more fully set forth. i The novel features of the inven ion will In order that my inventionimaybe the.

better understood, I will now progeed Scribe the same with reference to the 3 applied thereto; Fig. 2 is a. fragmentary,

transverse sectionalview taken through the supporting axle or spindle and illustrating the adjacent parts of the bearing; Fig.3 is

a longitudinal sectional view taken substantially centrally through Fig. 2; and Fig. 4" is a fragmentary sectional view illustrating certain details of my invention, as herein disclosed.

As disclosed in the accompanying drawings, I set forth an embodiment of In in.- vention as applied to a car axle and as t erein illustrated, 1 denotes an axle of any 0rdi nary or preferred construction reduced, as at 2, toafi'ord a spindle to accommodate the hub 3, which hub is preferably divided longitudinally into a plurality ofsections and is herein shown as comprising two such sections. Produced in the-inner f of the hub 3 and directed longitudinally Specification of Letters Patent. Patented J une 30, 1914. Application filed September 19, 1913- selial No. 790,689. i

which are adapted to be seated the bearin rollers 5, such bearings 55 bei 0' hel against endwise movement thro ifii 'the medium of the anti-friction'members M; j herein shown as" spherical bodies resting in the ti o'ned inthe walls of the grooves or c anoi's andextended transversely thereof, such claim-ale! grooves or channels 9-9 correspondingly produced in the hearings in a mhnne'r which is believed to be obvious.

Jhwardiy'directed projections 8 whereby portion of each of such bearings reduced,

mg embraced by the sleeves 11' suitably fixed in? the end of the hub and being provided with suitable race ways to acc'mmo- .-r 1;t gh anti-friction members 2-42 contact with such reduced porof the hub is provided with li hing 15 also formed of a plurality hnsjand adapted to hold the bearrhm re s; P slots-16 of less transverse diameter than the 5f and-through which\ the bights of such are adapted, to project in order to perly contact with the spindle 2. As Q disclosed, the hub 3 is adapted to rota set forth," such hub is provided at its opposite ends with the outwardly directed flanges 1919 of any proper configuration but herein set forth as in the simulation of a four.- pointed star and each of the points 20 are herein shown as provided with the opposi-tely disposed laterally projecting extensions orears 21. The flanges 19 are adapted to bear snugly against the web of the wheel 23- and'clamping rods 24 are adapted to extend through the projections 21 and the web izgherical'bodies being also extended within the' anti-friction memmrs 6-6 are opera-' afsi'lndicated at 10, such reduced portions be rrollers' e against displacement, such rovided with the elongated {segmental race members 8-3 suitably osi- .I-t'flisto be observed that the ends of the l fdseglnontalmembers 8 are provided with the we I i adjacentportions of the hearings or rollers.

with the wheel proper and as herein loo 23' whereby the flanges 19 are so held to the web 23 as to cause the hub to rotate with the heelproper, 'As herein set forth the wheel idedyazs is believed to be apparent clim but it is also-thought 11 obvious that should the wheel be provided with spokes that the points 19 can be suitably locked thereto, in a manner similar to the clamping means herein set forth.

From the foregoing description it is thought to be obvious that a roller bearing constructed in accordance with my invention. is of an eitremely simple and conlifiiarativel inexpensie nature andis partic arly .we

adapted or use by reason of the convenience with which it may be applied in operative positionand 'ofgtlae mimmum amount of vfriction afl'ordedb'etwee'n-the parts, and it will also be obvious from the foregoing description that my improved roller bearing iscapable of some change and modification withoutematerial departure from the principles and scope of the invention and for this reason I do not wish to be understood as limiting myself tothe precisearrangement and formation of the several parts, herein shown, incarrying out my invention in practice.

I claim:

In combination with a hub having its inner wall provided with longitudinally di rected channels, rollers mounted in the channels and extended within the bore of the hub, said rollers being provided with annular grooves at substantially their longitudinal centers, segmental race members po- H sitioned within the bases of the channels of the hub and'disposed transversely thereof,

such members having their extremities pro vided with inwardly directed\projections, such members being wholly confined within the channels, and spherical bodies carried by the race members and projecting within the annular grooves of the rollers.
